Description

【０００１】
【発明の属する技術分野】
本発明は、多重給紙を検知する装置を有する、枚葉紙処理機械の紙差し板上の枚葉紙の側方を揃える装置に関する。
【０００２】
【従来の技術】
枚葉紙処理機械、特に枚葉紙輪転印刷機では、側方を真っ直ぐに揃えるべき枚葉紙が、側方に引き寄せられる動作の間に、斜めにされるという問題がある。
【０００３】
この問題を解決するために、支持ローラを紙差し板の中心と側方引き寄せ装置の作動進路との間の交差点に配置すること、および多重給紙を検知する装置をこの支持ローラに設けることが、ドイツ特許出願公開第3536533号明細書によって既に知られている。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、多重給紙を検知する装置を備えた、枚葉紙の側方を真っ直ぐに揃える装置を提供することにある。
【０００５】
【課題を解決するための手段】
この目的は、本発明によれば請求項１の特徴項によって達成される。すなわち、第２の引き寄せ装置が、第１の引き寄せ装置に対向して配置されており、多重給紙監視装置を有する押圧ローラが、枚葉紙を安定させるために、各々の引き寄せ装置にそれぞれ付属している。
【０００６】
本発明の利点は、多重給紙の検知装置が保持機能を有しており、そして、この目的のために、最も好ましい保持点に、すなわち枚葉紙の、引き寄せ装置にそれぞれ対向する側部上に配置されているということである。
【０００７】
この方策のおかげで、枚葉紙の側方を揃える際に枚葉紙を平行に案内するための、枚葉紙搬送方向の保持力は、非常に小さくて済む。
【０００８】
２つの側方引き寄せ装置のこの配置によって、枚葉紙を真っ直ぐに揃えることが、左側の側方ストッパのみならず右側の側方ストッパによっても可能である。側方引き寄せ装置の領域における、２つの多重給紙監視装置の配置は、２枚の給紙および多数枚の給紙の他に、付加的に折り曲げられた枚葉紙角部を検知する位置にある。
【０００９】
側方の揃えの際の枚葉紙のスライド特性を良好にするために、多重給紙監視装置は、自由に回転できるように支持されている対向ローラと共働する押圧ローラを有している。
【００１０】
【発明の実施の形態】
次に、本発明の実施の形態について図面を参照して説明する。
【００１１】
枚葉紙輪転印刷機1は、給紙装置2と、若干の印刷ユニット3,4、すなわち少なくとも１つの印刷ユニット3または4と、排紙装置6とを有している。枚葉紙9は、給紙装置2の給紙パイル7から、分離ユニット11により分離され、給紙板12上を枚葉紙輪転印刷機1に搬送される。給紙板12の、印刷機側の端部には、枚葉紙9の側方を揃える側方引き寄せ装置10と、枚葉紙9の前縁を揃えるための前方ストッパ13とが備えられている。揃え工程が行われた後、枚葉紙9は、この枚葉紙9を枚葉紙輪転印刷機1の給紙胴16のくわえづめ装置15に渡す、揺動可能に設けられている搬送用くわえづめ14によって受け取められる。
【００１２】
側方引き寄せ装置10は、揃えるべき枚葉紙9に保持力を及ぼすことを可能にするために特に吸引空気が作用する２つの引き寄せ案内レール17,18を備えている。引き寄せ案内レール17,18は、給紙板12の、枚葉紙9の搬送面の下に、互いに対向して、揃えるべき枚葉紙の側方の縁部領域にそれぞれ配置されている。
【００１３】
図２中の矢印で示されている枚葉紙搬送方向に見て左側と右側にそれぞれ、枚葉紙9を選択的に揃える側方ストッパ19,21が備えられている。
【００１４】
枚葉紙搬送方向に見て、引き寄せ案内レール17,18の直ぐ前にそれぞれ、給紙板12の搬送面の下方に自由に回転できるように支持されている対向ローラ24,26と共働する、機械サイクルで周期的に揺動可能な押圧ローラ22,23が備えられている。
【００１５】
押圧ローラ22,23と、これにそれぞれ対向する対向ローラ24,26は、枚葉紙搬送方向に対して横方向に、すなわち側方揃えの方向に回転できるように支持されている。
【００１６】
枚葉紙輪転印刷機1の方向に搬送される枚葉紙９は前方ストッパ13に到達し、その場所で、後続の胴、例えば給紙胴16の周方向に揃えられる。次に、枚葉紙9は、側方ストッパ19により枚葉紙9の側方を揃えるために、吸引空気が作用する引き寄せ案内レール17により、側方ストッパ19に向かって引き寄せられる。
【００１７】
枚葉紙9の前縁の揃え、または周囲の揃えの後、多重給紙を検知するために、そして同時に、引き寄せ案内レール17による側方揃えの際に枚葉紙9を案内するために、制御用の押圧ローラ23がカム28により、回転可能に支持された対向ローラ26の領域の枚葉紙9上に下げられる。
【００１８】
この実施形態で左側に配置された側方ストッパ19に向かって引き寄せられる枚葉紙9は、枚葉紙を安定させるために、枚葉紙9が前方ストッパ13から跳ね返ることまたは離れることを回避するように、他の側方上に配置された押圧ローラ23と対向ローラ26によって案内される。
【００１９】
押圧ローラ22,23は、同時に、多重給紙監視装置を備えており、然るべき導線により、枚葉紙輪転印刷機1の制御コンピュータ31に接続されている。この枚葉紙輪転印刷機は、多重給紙が検知された場合には、例えば制御コンピュータ31により停止される。
【００２０】
揃えられるべき枚葉紙９をより良好に案内するために、押圧ローラ22,23を同時に作動させてもよい。
【００２１】
この方策により、多重給紙を同時に２つの異なる測定箇所で検知することが可能であり、これにより、測定の信頼性が向上する。同時に、作動させられている引き寄せ案内レール17または18のそれぞれに対向する側部に生じる、折り曲げられた枚葉紙の角部を検知することも可能である。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for aligning the sides of a sheet on a sheet feeding board of a sheet processing machine having an apparatus for detecting multiple sheet feeding.
[0002]
[Prior art]
In a sheet processing machine, particularly a sheet rotary printing machine, there is a problem in that a sheet that should be aligned sideways is skewed during the operation of being pulled sideways.
[0003]
In order to solve this problem, it is possible to arrange a support roller at the intersection between the center of the paper feed plate and the working path of the side pulling device, and to provide a device for detecting multiple paper feeds on this support roller. Is already known from German Offenlegungsschrift 3536533.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide an apparatus for aligning the sides of a sheet straightly, which includes an apparatus for detecting multiple sheet feeding.
[0005]
[Means for Solving the Problems]
This object is achieved according to the invention by the features of claim 1. That is, the second pulling device is arranged opposite to the first pulling device, and a pressing roller having a multiple paper feed monitoring device is attached to each pulling device in order to stabilize the sheet. is doing.
[0006]
The advantage of the present invention is that the multi-feed detection device has a holding function and, for this purpose, at the most preferred holding point, i.e. on the side of the sheet, respectively facing the drawing device. It is that it is arranged in.
[0007]
Thanks to this measure, the holding force in the sheet transport direction for guiding the sheets in parallel when aligning the sides of the sheets is very small.
[0008]
With this arrangement of the two side-drawing devices, it is possible to align the sheets straightly not only with the left side stopper but also with the right side stopper. In the area of the side pulling device, the arrangement of the two multiple paper feed monitoring devices is in a position to detect an additionally folded sheet corner in addition to two paper feeds and a large number of paper feeds. is there.
[0009]
In order to improve the slide characteristics of the sheets at the time of lateral alignment, the multi-feed monitoring device has a pressing roller that cooperates with a counter roller supported so as to be freely rotatable. .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0011]
The sheet-fed rotary printing press 1 includes a paper feeding device 2, some printing units 3 and 4, that is, at least one printing unit 3 or 4, and a paper discharge device 6. The sheet 9 is separated from the sheet feeding pile 7 of the sheet feeding device 2 by the separation unit 11 and is transported to the sheet rotary press 1 on the sheet feeding plate 12. At the end of the paper feed plate 12 on the printing machine side, a side pulling device 10 that aligns the sides of the sheet 9 and a front stopper 13 for aligning the front edge of the sheet 9 are provided. . After the aligning process is performed, the sheet 9 is conveyed so that the sheet 9 is passed to the holding device 15 of the sheet feeding cylinder 16 of the sheet rotary press 1 and is provided so as to be swingable. Received by Mouth 14.
[0012]
The side pulling device 10 comprises two pulling guide rails 17, 18 on which suction air acts in particular in order to be able to exert a holding force on the sheets 9 to be aligned. The drawing guide rails 17 and 18 are respectively arranged in the edge region on the side of the sheet to be aligned, opposite to each other below the conveyance surface of the sheet 9 of the sheet feeding plate 12.
[0013]
Side stoppers 19 and 21 for selectively aligning the sheets 9 are provided on the left side and the right side as viewed in the sheet transport direction indicated by the arrows in FIG.
[0014]
Cooperating with opposed rollers 24 and 26 that are supported so that they can freely rotate below the conveying surface of the sheet feeding plate 12, respectively, immediately before the pulling guide rails 17 and 18 when viewed in the sheet conveying direction, There are provided pressure rollers 22 and 23 that can be swung periodically in a mechanical cycle.
[0015]
The pressing rollers 22 and 23 and the opposing rollers 24 and 26 respectively opposed to the pressing rollers 22 and 23 are supported so as to be able to rotate in a lateral direction with respect to the sheet transport direction, that is, in a laterally aligned direction.
[0016]
The sheet 9 conveyed in the direction of the sheet-fed rotary printing press 1 reaches the front stopper 13 and is aligned therewith in the circumferential direction of the subsequent cylinder, for example, the sheet feeding cylinder 16. Next, the sheet 9 is drawn toward the side stopper 19 by the drawing guide rail 17 on which suction air acts in order to align the sides of the sheet 9 by the side stopper 19.
[0017]
After detecting the leading edge of the sheet 9, or after aligning the surroundings, to detect multiple feeds, and at the same time, to guide the sheet 9 during lateral alignment by the pulling guide rail 17, The control pressure roller 23 is lowered by the cam 28 onto the sheet 9 in the area of the opposed roller 26 that is rotatably supported.
[0018]
In this embodiment, the sheet 9 that is drawn toward the side stopper 19 arranged on the left side avoids the sheet 9 from bouncing off or moving away from the front stopper 13 in order to stabilize the sheet. Thus, it is guided by the pressing roller 23 and the opposing roller 26 arranged on the other side.
[0019]
The pressure rollers 22 and 23 are simultaneously provided with a multiple paper feed monitoring device, and are connected to the control computer 31 of the sheet rotary printing press 1 by appropriate conductors. This sheet-fed rotary printing press is stopped by, for example, the control computer 31 when multiple paper feed is detected.
[0020]
In order to better guide the sheets 9 to be aligned, the pressing rollers 22, 23 may be operated simultaneously.
[0021]
This measure allows multiple feeds to be detected simultaneously at two different measurement locations, thereby improving measurement reliability. At the same time, it is also possible to detect the corners of the folded sheet that occur on the side facing each of the activated pulling guide rails 17 or 18.
